injuries tovships hulls, occasioned, for in-` w stance, b explosions, collisions, etc..i

One o the objects of the invention issto provide repair means of thisI 'characterwhich may be readily stored in compact form on board ship, and which when needed,

15 may be quickly applied to the injured ponA tion of the ship. l Other objects are to provide a? repair which can be' made substantially. Watertight, which will resist the pressure and strains, which may. be conformed to the portions of the hull to which it is applied, and wlhich canybe'y readily and rmly secured in .p ace. l .j e

Briey stated, the invention Icomprises 25 what I have .termed a atch of flexible material which is suitab y reinforced and which is provided with means by which the same may be positioned and supported to cover an injury in a ships hull. This patch is normally rolled in compact 'form and in case of injury is unrolled at the side of the ship so as to cover the damaged area, Thel reinforcements are preferably transversely disposed so as netto interfere With'this rolling and unrolling of the patch and the supporting means are so disposed that they Will remain on the outside of the roll when the patch is rolled up in compact form.

Another feature of the invention is the M provisioirof means for engagement Withthe reinforcements at the inside of the shlps hull to secure the patch more firmly in'place.. @ther features of the invention are spei cial reinforcements for application over the shape the patch to `the ships hull.

no .tures will be made clear in thefollovving specification and accompanyingefdravvings which illustrate thev invention embodied;

a practical form. l j In these dravvings-:-- h5 Figures 1 and 1a are fragmentary views of! the rail of the ship or any other convenient point of attachment. Cables 23 and 24 attached respectively to the upper corner port1ons and lower side portions of the patch provide means for holding the sides of. the

patch in place against the ships hull and also provide means by which the patch may .be shifted longitudinally fore or aft' To facilitate handling these"fore and aft cables may be joined inJ a common cable as` cables 26-27 attached respectively to the corner and intermediate portions at the lower edge of the patch and which cables may be united to a common shackle 28 from which a cable 29 extends under the hull of the ship to the opposite side thereof. The patch may also be steadied at the bottom by cables 30 connected `to the lower corner portions of the patch and designed to be carried on divergent. angles beneath the keel to the opposite side of the ship. Said cables 30 may be` formed as continuations of the upper cables 20.

In practice the patch is rolled into compactform and stored' in a conveniently accessible place, such as on the hatch covers, from which point it may be readily carried fore and aft or to.. either side as the case may require. The patches are rolled from the bottom upward and usually with the inside of the patch toward the inside of vthe roll and the ends of the supporting and steadying cables are preferably left exposed' as indicated, in Fig. 15. In case of an injury to the ships hull, as by torpedoing or the like,- the rolled patch is carried to the point of injury and then after hooking the supporting cables over the rail or other convenient support, the roll is carried outward' by sui-table tackle and allowed to unroll in such a position as to cover the damaged area. The patch is lowered farenough out from the side of the ship to enable the same to pass clear down below the injury, the inward rush of water into the injured portion 0f the hull being ordinarily suiicient to carry the patch inward into position over the aperture. Before the roll is dropped overboard the fore and af stays and the connections forjpulling the patch downward are usually carried to convenient points on the ship from where they can be drawn' taut as soon as the patch unrolls and covers the hole in the ships side. The bottom cable or cables may be placed by retaining the ends of said cables when the roll is cast over and carrying such ends around the bow'or stern, whichever 1s nearest, as the case maybe, and then drawing sald cable taut from the oppositeside of the ship.

The reinforcement prevents the patch from vgiving way under the pressure of the water and these reinforcements may be used also A rial l33 which may be lowered so as to cover the edge portions of the main patch as indicated in Figs. 1 and 1a and be steadied at the top and bottom as by means of suitable cables or connections 34.

Other external reinforcements may be provided asthe reinforcing plates illustrated at 35 in Figs. 1 and 5, said plates being applied over the patch and being of sutilcient size to lend the necessary strength and reinforcement to the patch. For convenience in handling and storing, these reinforcement ,plates may be made in sections as indicated in Figs. la, 13 and 14, said sections 35, 35b being joined when needed, for instance, by means of lugs 36 on one section engaging in properly disposed openings 37 in the other section. These reinforcements may also be steadied at the top and the bottom as indicated at 38 in Figs. 1 and la.

At certain points in the ships hull, for instance, at the bow and stern, special reinforcing means may be necessary to hold the patch properly fitted to the ships hull. For this purpose I may employ the shaping devices illustrated more particularly in Fig. 10 and comprising in the first instance concavely curved shaping elements 39 for holding the patch against bulging on convexed portions of the hull and the convex shaping devices 40 acting ina similar fashion to press the patch against concaved portions of the ships hull. These patches may also be of spring metal and bowed as indicated in l a vessel, means for supporting and positioning said patch over the damaged portion, and a separate auxiliary patch of flexible material engageable over the edge portions of the main 'patch and provided with means for positioning an'd supporting the same in reference to the main patch.

2. Ship repairing means comprising a naaacc patch of flexible Water-tight material provided with means for supporting the same over the damaged portion of a vessel to stop the inflow of water, and anI imperforate reinforcing plate applied over the outside of said patch for taking the strain of pressure o the leak stopping patch.

3.' Ship repairing means comprising a pat/oh of flexible material provided with means for supporting the Same over the damaged portion of a vessel, and a curved shaping member applied over the outside of said patch for conforming said patchY to the curvature of the hull' ofthe vessel.

4. Ship repairing means comprising a patch of flexible material provided with means for supporting'-.the same over the damaggged portion of a vessel, and a curved spring shaping member applied over the patch and yieldingly conforming the patch to the curvature of the hull.`

5. Shi repairing means comprising a patch o exible material provided with means for supporting the same over the damaged portion of a vessel, a curved spring shaping member for yieldingly holdin the patch over curved portions of the s ip'is hull, supporting means for said spring shaping device oifset from the contacting plane of such device whereby to force said shaping device into engagement with the patch.
